It’s generally recommended to schedule HVAC maintenance at least once a year. Ideally, you should have your system serviced twice a year—once before the cooling season in spring and once before the heating season in fall. Regular maintenance helps ensure your system runs efficiently, extends its lifespan, and can prevent costly repairs down the line. Additionally, changing filters every 1-3 months can help maintain air quality and system performance.

If your HVAC system isn’t working properly, start by checking the thermostat to ensure it’s set correctly and in the right mode. Change the filter if it looks dirty, as a clogged filter can restrict airflow. Inspect the circuit breaker to see if the HVAC system has tripped and reset it if necessary. Look for air leaks around windows and doors that might affect performance, and listen for any unusual noises that could indicate specific issues. Make sure all supply and return vents are open and unobstructed, and clear the outdoor unit of any debris like leaves or dirt. Lastly, check for ice on the coils, which can indicate a refrigerant issue or airflow problem. If these steps don’t resolve the issue, it’s best to call a qualified HVAC technician for professional diagnosis and repair. Regular maintenance can help prevent many common problems.
